'.It is fixed f. at. one endto a clamp 6 ofA anysuitable form on the table,

- and 'at the other end is attached; byfmeans of a clamp? orotherwise, to a Weight 8 or other device adapted to exert a constantten- I Sionuponfthe mesh. `Instead ofmakingthe 1 clamp 7 to extend continuouslyfrom edge to` edge of thewire meshlmay make it in Sec-` Y tions and apply a tension device to each Sec- `tiongbut I prefer to accomplish the same purpose by usinga flexible clampand a number of` tension devices at different points of its` length, l as illustrated in Fig.` 4.' Themesh.` proper extends under a `roller 9, suitably` mounted onlthe roll-carriage, but `preferably t carried on a rock-lever or vother adjustable E device 10, WhichWhen the rock-lever is ein` Oe at 11 andhas an arm 12, tted with an antiricticn- `rollerfl), traveling on theunder Side of a' guide-strip 14. This guidestrip has atfthe ployed is pivoted on the roll-carrie.`

" ends suitable adjusting v mechanism."` 15, by i Which its vert-ical position and its inclination` j maybe varied.- The purpose of thusmount#` i ing theroller 9 yisvthat by raising the guide#y stri the roller 9 is permitted torise, and thus to a 10W the mesh to assume apositionhigher" from the table, and by loweringit the roller 9 is brought nearer to the table. "-If' the .guide-Strip beset at an inclination, as Shown in dotted `lines in Fig". 1, `the rollerQ Will be 1broughtnearer` toV the tabiewward the @naar the operation, and this isgenerally desirable, because it compensates for the changes'in the weight of the mass'of glass, which-being heavy at the beginning of the speading of the sheet 5 tends to cause the sheetto sag, which tend-` ency gradually decreases 'as the operation` except` in respect of those of the claims hereto appended inwhich such variation is spe! A `cifica ymentioned.

In the practice of my invention I adjust the wire mesh, as shown in the drawings, and then, having retracted the roll to the rear end of the table, I place a mass 16 of Ymolten glass between the guns 4 and move the roll-carriageforward in the direction of the arrow. As the roll-carriage advances it will hold the wire mesh in a state of tension and at exactly the distance desired above the level of the table, and the roll will-spread the glass into the form ofla sheet, pressingit through the `interstices of the Wire mesh against the surface of the table. As the carriage advances farther portions of the wire desired horizontal position above the table, and when the end of the sheet has been reached a trip-arm 17 on the clamp 7 will preferably yengage the portionlS of the rollcarriage and will automatically release the clamp from the wire mesh, so that the loose end of the lmesh will be embeddedin the glass. The glass sheet is then put inthe annealing-oven.

In Iiigs. 5, 6, and 7 I have illustrated an apparatus in which the wire mesh is held transversely of the table. As therein shown, there is provided on one side of the table ya fixed clamp 6a' of suitable form and on the other a roller 9a, over whichv the edge of the wire mesh passes and upon which the mesh is held by the clamp 7 a, which is yieldingly secured to a depending extension or bracket fastened t'o the table by tension-springs 8a.

5o My invention has important advantages. By holding the wire' mesh under constant ing-surface I am enabled to form the iinished one operation. After ,the wire ha' s-touched Oxidation of the'wire is thereby prevented,

ubbles than has heretofore'been possible.

he body of molten glass is in contact with successive portions of the meshy forv 'some lace, so thatbefore the glass is spread at any mesh will be brought progressively into the tension at the desired distance fromthe formsheet of wire-glass from one batch of metal in the glass it isnot again exposed to the air.

nd sheets are thus made muchfreer from g Moreover, when my invention is practiced inie before the actual rolling pressure takes given place themesh has had time to assume the temperature of the molten glass and to.'

have expanded to its full extent.

Iam aware that it hasbeen proposedl to in- I., corporate thewiresofa mesh inribs formed on one or both sides ofi Aa glass plate. In

forming such plates the .mesh which corre-.-

`In operating such an apparatus thewire mesh is not held above the formingfsurfaceA and in spaced relation thereto applied to such mesh. a

The method of making wire-glass which f consists in placing the mesh under tension to support it above and in spaced relation above a forming-surface, pouring moltenl glass on the wire mesh, causing glass to pass through interstices of the mesh and embed the same in the body of the glass, and maintaining the mesh under tension'n substantially thel same spaced relation while being .embeddedl in the glass.
